Because of the disposition of thepins IS in the Figure 5 is a plan view of the base of the gate. base Il, and of the disposition of the walls 16 and In the drawing, as bestshown in Figure 1, a H, the members l2 are evidently well adapted to 55resist displacement or overturning even though they are not castintegral with the base H.

The parts H and i2 may be cast and cured at some convenient point, andtheir shape and relatively low weight facilitate their transportationover fields, even in the spring when the soil is Wet and soft, to theservice location.

Should the soil settle or become materially disturbed, due to unusualweather or flood conditions, it is obvious that the water gate of thisinvention is adapted to be readily disassembled and re-set.

Also, should a part become worn or damaged, that part may be readily andinexpensively replaced from stock parts Without renewing the wholestructure.

It has been found that the combination of a fiat slab for a sill, andthe outwardly and rearwardly diverging aprons produce a flow conditionthat does not encourage erosion of the soil about the gate.

Because of the ease with which the gate 99 may be disassembled,transported, and assembled in position, it is obvious that it lendsitself peculiarly to the demand for the temporary placing of gates ordams, and to the shifting of gates as flow-conditions or flowrequirements change in service.

The parts i2 are obviously interchangeable. When the side members areprovided with apertures that extend the full height of the toe andWalls, or are provided with similar top and bottom apertures, they arereversible so that it is often possible to keep a gate in service byreversing a side member to bring the damaged portion to a position inwhich it does not materially affect flow control. Thus, should the lowerportion of a toe or wall become damaged, the side member may be reversedto put the damaged portion above the water line.

It is also obvious that the pins in the slab may be arranged extendingthrough the slab to provide anchorage in the soil, and to also make theslab reversible in service, as is indicated at 2| in Figure 3.

It will of course be understood that many changes may be made andnumerous details of construction may be varied through a wide rangewithout departing from the principles of this invention and it istherefore not the purpose to limit the patent granted hereon otherwisethan necessitated by the scope of the appended claims.

What is claimed is:

1. A water gate for irrigation ditches, said water gate comprising abase slab, a pair of spaced side members removably seated on said slab,each of said side members comprising a pair of substantially similar andintegrally formed and inwardly converging walls, said walls beingprovided with vertically extending apertures, and anchoring meansentered in said apertures and secured to said base whereby said sidemembers are secured against side movement and may be removed byvertically lifting them to clear said anchoring means.

2. A water gate for irrigation ditches, said water gate comprising abase, a pair of spaced side members removably seated on said base, asealing material between said side members and said base, said sidemembers each comprising a pair of substantially similar and integrallyformed and inwardly converging side walls, said side walls beingprovided With vertically extending apertures, a sealing material in saidapertures, a plurality of upstanding pins entered in said apertures andimmersed in said sealing material in said apertures, said pins beingsecured at their lower ends to said base, said side members beingremovable by vertically lifting them clear of said pins.-

3. A water gate for irrigation ditches, said water gate comprising abase, a pair of similar and interchangeable and reversible side membersremovably seated on said base in opposed spaced relation to each other,said side members each comprising a pair of substantially similar andintegrally formed and inwardly converging walls, and anchoring meanssecured to said base and slidably entered in said walls.

4:. A water gate for irrigation ditches, said water gate comprising afiat base slab having anchoring pins projecting normally from the upperand lower faces of said slab, a pair of spaced and interchangeable andreversible side members removably seated on the upper face of said slaband housing the pins projecting from that face, said side members eachcomprising a pair of substantially similar and integrally formed andinwardly converging walls, the pins projecting from the upper face ofthe slab being vertically alined with the pins projecting from the lowerface of the slab.
